Audio / Re: how to cut the end of a sound?

Nevermind, I just solved it myself:

buffer.getSamples() + cut determines the starting position of the new buffer. So of course I just want buffer.getSamples() here to start from the beginning (and not cut the beginning.
buffer.getSampleCount() - cut is the number of remaining samples. If I didn't cut in the beginning by not adding cut to the starting point, it will cut the audio at the end, just like intented.

Audio / how to cut the end of a sound?

« on: May 07, 2015, 11:07:20 pm »

hey guys!

I'm recording a sound, unfortunately it puts like 0.5 seconds of non-recorded silence at the end of the recording.
I want the recording to loop seamlessly.
I found this code which cuts the sound from the beginning:

sf::SoundBuffer withoutSilence;
const std::size_t cut = buffer.getSampleRate() * buffer.getChannelCount() * 0.5f;;
withoutSilence.loadFromSamples(buffer.getSamples() + cut, buffer.getSampleCount() - cut, buffer.getChannelCount(), buffer.getSampleRate());

I then feed the new buffer appropriately to create, play and loop the sound.
I don't quite understand the loadFromSamples function. It successfully cuts the sound, but from the beginning instead from the end.

Any ideas?
Thank you
Temophor
